[linux-audio-user] JACK and memory

Hi, I'm desperately trying to get my 1400MHz Pentium M with Debian Sarge to behave just a little like my old 66MHz BeOS system in terms of audio. But I keep running into troubles. I think I have the latency under control with kernel 2.6.13 and realtime-preempt, but I've got some stability problems (probably network related), so I'm working with kernel 2.6.12.5 unpatched. Right now my problem is that as JACK seems to work for test cases, but as soon as I want to do real work all JACK related programs starts to consume huge amounts of memory, which prevents me from doing any real work. System: Debian Sarge with some DeMuDi packages. Kernel 2.6.12.5 with realtime-lsm module ALSA 1.0.9rc2 libc6 2.3.2.ds1-22.demudi1 (NPTL 0.60 bug fix) libasound2 1.0.9-2 jackd 0.99.51-1 JACK starts fine with: $ /usr/bin/jackd -u -R -d alsa -d hw -r 44100 -p 2048 -n 2 ...(or via qjackctl), and simply things like playing xmms and small samples work. Even a minimal Timidity configuration with only freepats works, and I can make Rosegarden4 play midi through Timidity. But then the fun stops. All these applications takes enormous amounts of memory. All I have to do to trash my system is start JACK, and then start qsynth (but doing nothing with them). Is this memory frenzy normal? Peter
